For Property Tax Lenders & the Tax Industry
Delinquent property tax accounts and tax suits across Texas, joined to the appraisal record and refreshed daily. Every account carries a lender-eligibility flag, and where the county record names a mortgage, the loan is on the record too. Built for property tax lenders, protest firms, servicers, title and tax professionals.
Test keys are issued to qualified Texas property tax lenders — tell us about your operation and we’ll set you up with the live sample. Test keys open the sample; working keys belong to account holders.
Who it's for
Property tax lenders
Nobody automates this for you today: you buy a static list, your people scrub it, dedupe it and load it, and it starts going stale the day it lands. Agentix is the automation — finished records in your system every morning, with suit and judgment status, bankruptcy and deferral flags, exemptions, the lender-eligibility screen and the mortgage on record already applied. Your people work loans, not lists.
Protest firms
The appraisal file chase is manual today — owner, property use, market, land and improvement values and exemptions pulled county by county while the protest clock runs. Agentix delivers that file by county, refreshed daily: current values and exemptions in hand when the window opens, not after it closes.
Servicers, title and tax professionals
Watching accounts move is manual work today, and the move is usually noticed late. The daily change file automates the watch — tax suits, judgments and payoffs land in your morning file, so what moved, was sued or was paid surfaces the day it happens.
We already have
- 57,890 tax suits and judgments in Angelina, Caldwell, Collin, Dallas, Denton, Ector, Harris, Hood, Midland, Montgomery, Sabine, Tarrant, Travis, Trinity counties: cause number, suit status (pre-suit, in suit, judgment) and judgment date. The county has already sued to collect — the pressure is live and the clock is running. This is a borrower who needs a way out now, not someday.
- Mortgage on record — the original loan amount, the balance still owed today, and the loan's status, open or closed. A live pressure point: the property already carries a lien, so a tax loan has to be structured around what's ahead of it.
- 761,456 delinquent tax accounts in Angelina, Bell, Bexar, Caldwell, Collin, Dallas, Denton, Ector, Gillespie, Grimes, Harris, Hood, Kendall, Lubbock, Midland, Montgomery, Sabine, Tarrant, Travis, Trinity, Williamson counties: amount owed, first year delinquent, years delinquent, tax account number, and whether penalty and interest are included. Penalties and interest keep compounding every month the bill goes unpaid — every month a borrower waits, the hole gets deeper, and the case for the loan gets stronger.
- Daily change files, so you can stop mailing accounts that were paid and start on new ones the day they appear — yesterday's dead lead is gone before you waste a call on it.
- Bankruptcy and deferral flags as the tax office reports them — a legal wall around the account, flagged before you spend a dollar working the lead, and flagged again the day it lifts.
- Exemptions from the appraisal district: homestead, over-65, over-65 surviving spouse, disabled person, disabled veteran and tax deferral. The over-65 and surviving-spouse homesteads are loans the law won't let you make — screened out before your team wastes effort on them.
- Owner and property details: owner name, mailing address, absentee and out-of-state owner, situs address, property use, market value, land and improvement value, deed date and instrument.
- Foreclosure notices and suits (2,852 in Bexar, Dallas, Denton, Harris, Johnson, Kaufman, Montgomery, Rockwall, Tarrant), so you can see a mortgage default on the same property — another pressure point, already in motion.
Counts are what we deliver today (2026-11-05), not estimates. See Coverage for every county.
Stop buying lists. Start receiving records.
A property tax lender's data still usually starts as a list bought once a month. Ours doesn't. Tax Desk is a finished feed: the processing a list leaves to your team is already done before a record reaches you.
- The old way. You buy a static list, then your own people scrub it, dedupe it, match it to properties and load it into your system — and it starts going stale the day it lands, as accounts get paid and new suits get filed. Next month you buy it again and process it again.
- The finished record. Every account arrives already tied to its property and owner, with suit and judgment status, bankruptcy and deferral flags, exemptions and the lender-eligibility screen applied — and the loan on record attached where the county record carries it. It loads as work, not as a project.
- Current every morning. The daily change file drops the accounts that were paid and adds the ones that just surfaced, so your system stays current without another list purchase and without another processing round.
- Fitted to your system. Take it by API, by daily file, or as CSV in the layout your loan system or mail house needs. The feed meets your system where it is; your system doesn't bend to a list vendor's format or calendar.
No list vendor's calendar to be beholden to, no in-house list processing: your people's time goes to working loans, not cleaning data.
How it's delivered
- API with your own key: pull by county and record type, only what changed since your last pull. See the API docs.
- Bulk files: one gzip file per county and record type, plus a daily change file.
- Daily email and CSV download for account holders, for the counties you pick.
- Custom layouts for your mail house or loan system on request.
Lender-eligibility fields
Every delinquent account carries a lender-eligibility flag. It marks over-65 homesteads, tax deferrals and bankruptcies as not eligible, and notes disabled owners whose loan documents must mention the deferral option. You make the final call.
| Field | What it tells you |
|---|---|
lender_eligible | true or false, from the rules above |
ineligible_reasons | Why an account was marked not eligible, for example over_65_homestead, tax_deferral_33_06 or bankruptcy |
notices | What the loan documents must mention, for example disabled_owner_33_06_notice_required |
exemptions | Homestead, over-65, disabled, disabled veteran and tax deferral, from the appraisal district |
tax.suit_status, tax.judgment_date | Pre-suit, in suit or judgment, and the judgment date |
tax.bankruptcy, tax.deferral | As the tax office reports them |
